I never understood why people would use it The benefits I see are; - if the hair-trigger shutter is problematic - save battery with no VR during focus, but VR often helps me compose and I think works better if engaged before shutter release
I would think that true single servo would give a more accurate focus than your method of press and release. Have you found similar results?
